如何使用#pragma message()以便消息指向文件(lineno)? [英] How can I use #pragma message() so that the message points to the file(lineno)?

问题描述

为了将待办事项"项添加到我的代码中，我想在编译器输出中添加一条消息.
我希望它看起来像这样:

In order to add 'todo' items into my code, I want to put a message in the compiler output.
I would like it to look like this:

c:/temp/main.cpp(104): TODO - add code to implement this

为了利用Visual Studio构建输出功能，通过双击来导航到相应的行.

in order to make use of the Visual Studio build output functionality to navigate to the respective line by double-clicking it.

但是__LINE__宏似乎扩展为int，不允许写入

But the __LINE__ macro seems to expand to an int, which disallows writing

#pragma message( __FILE__ "("__LINE__"): ..." )

还有其他方法吗?

推荐答案

以下是允许您单击输出窗格的一种:

Here is one that allows you to click on the output pane:

(那里还有其他一些不错的技巧)

 // Statements like:
 // #pragma message(Reminder "Fix this problem!")
 // Which will cause messages like:
 // C:\Source\Project\main.cpp(47): Reminder: Fix this problem!
 // to show up during compiles. Note that you can NOT use the
 // words "error" or "warning" in your reminders, since it will
 // make the IDE think it should abort execution. You can double
 // click on these messages and jump to the line in question.

 #define Stringize( L )     #L 
 #define MakeString( M, L ) M(L)
 #define $Line MakeString( Stringize, __LINE__ )
 #define Reminder __FILE__ "(" $Line ") : Reminder: "

一旦定义，就这样使用:

Once defined, use like so:

#pragma message(Reminder "Fix this problem!") 

这将创建如下输出:

C:\ Source \ Project \ main.cpp(47):提醒:解决此问题！

C:\Source\Project\main.cpp(47): Reminder: Fix this problem!
